Laravel-Admin Storage使用 ucloud
作用：laravel-admin 自带的images 和 multipleImage控件可直接上传到ucloud
Storage 也可直接使用 示例：
\Storage::disk('ucloud')->put('images/file.jpg', file_get_contents("public/images/loading.gif"));
//遇到一个坑 影响不大 mark一下
如果先拿这个文件名去浏览器访问了一下（提示文件不存在） 再去上传那么会上传不上去，很奇怪！！
三个新文件 （先放 App\Providers\UcloudLaravelAdmin 目录下吧）

3、UfileServiceProvider.php
<?php

use Illuminate\Support\ServiceProvider;
use League\Flysystem\Filesystem;
class UfileServiceProvider extends ServiceProvider {
public function boot() {
/*
* extend方法的第一个参数是驱动名称，
* 第二个参数是获取$app和$config变量的闭包。
* 该解析器闭包必须返回一个League\Flysystem\Filesystem实例。
* $config变量即为 配置文件config/filesystems.php中为特定磁盘定义的选项。
* 创建好注册扩展的服务提供者后，就可以使用配置文件config/filesystem.php中的ucloud驱动了
*/
\Storage::extend(
'ucloud',
function ($app, $config) {
$ufileAdapter = new UcloudUfileAdapter(
$config['bucket'],
$config['public_key'],
$config['secret_key'],
$config['suffix'],
$config['prefix']
);
$fs = new Filesystem($ufileAdapter);
return $fs;
}
);
}
public function register() {
}
}
修改2个文件
1、config/app.php 中providers数组里 添加
App\Providers\UcloudLaravelAdmin\UfileServiceProvider::class
2、config/filesystems.php disks数组里 添加
'ucloud' => [
'driver' => 'ucloud',
'bucket' => '',
'public_key' => '',
'secret_key' => '',
'suffix' => '.ufile.ucloud.cn',//图片上传地址
'prefix' => '',
'url' => env('OSS_HOST'),//图片访问CDN地址
],
3、config/admin.php upload 数组里 更改
'disk' => 'ucloud',
需要安装的组件
